Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39958, here are decompositions:
- 5 + 39953 = 39958
- 29 + 39929 = 39958
- 71 + 39887 = 39958
- 89 + 39869 = 39958
- 101 + 39857 = 39958
- 131 + 39827 = 39958
- 137 + 39821 = 39958
- 167 + 39791 = 39958
Showing the first eight; more decompositions exist.

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
